Complete parts a through c below Click the icon to view the regression output a. Calculate the muitiple coefficient of determination R2 05412 (Round to four decimal places as needed) b. Test the signto anco of the ovorall regression model using a = 0 05 State the nul and aiternative hypotheses. Choose the correct answer below ? ?. Ho: ß,-ß2-ß3-0 (No relationship between the variables) H 1: At least one ßit0 (Relationship exists between the variables) Ho: ?1 # ?24 ?3 (Relationship exists between the variables) H 1: ?,-?2-?3 (No relationship between the variables) D. Identify the value of the test statistic F14.16 (Round to two decimal places as needed.)

Explanation / Answer

SSE = 8362.4400 SST = 18228.09 n= 40 k= 3 R2adj= 1-(n-1)*SSE/(SST(n-k-1)) = 0.5030
